Skill Creator God

Jake was a normal guy who played the wonderful game of league of legends, he always thought to himself: "Man! These skills are overpowered! If I had the ability to make and balance skills I'd do it much better", usually after dying for the 12th time and having 0 kills. One day he died in this game and as he was raging in real life, the sword struck him through his monitor, killing him! He awakes in another world where he was chosen to become the Skill Creator God, his job is to balance and provide skills to a normal fantasy world without skills or jobs prior to this. Will he prove himself as the all powerful skill creator? or will he just create an unbalanced mess?
